Description

20 - 30 mesh, Effective Size 0.67 mm - Sub-Angular White

Material Use:

GS 20 Silica Sand is a sub-angular, white silica sand used primarily as an abrasive media for sandblasting and surface preparation. It may also be incorporated into coatings or repair systems as a filler or traction additive.

System Components:

This product is typically used as a stand-alone abrasive media but can be combined with liquid coatings or primers where silica broadcast or anti-skid texture is needed. It may be used in conjunction with resinous flooring systems (epoxy, polyurethane, polyaspartic, etc.) for build-up, slip resistance, or improved durability.

Applications:

  • Abrasive blasting
  • Broadcast medium in resin floor coatings
  • Filler or bulking agent in repair mortars or slurries
  • Traction enhancement for coatings
  • Leveling or smoothing compound component

Application Details:

  • U.S. Sieve Profile: 55% retained on 20 Mesh, 42% on 30 Mesh, and 3% on 40 Mesh; AFS grain fineness number: 16.
  • Effective Particle Size: 0.67 mm
  • Uniformity Coefficient: 1.41
  • pH Range: 5.5 – 6.8
  • Specific Gravity: 2.65
  • Color: White
  • Grain Shape: Sub-angular

Special Notes:

  • Contains respirable crystalline silica (SiO₂ >99.5%) which poses a health hazard when inhaled. Always follow OSHA safety guidelines for silica dust exposure.
  • This material should not be used where silica-free abrasive is required.
  • Performance in a system (e.g., as broadcast media in coatings) will depend on compatibility with the resin or coating used.

No details were provided regarding UV stability, curing time, or temperature/humidity restrictions—these will depend on how it is used in a system (e.g., in combination with epoxies or urethanes). It is not a standalone coating or repair product but a mineral additive/media.
